Definition: The reverb filter does exactly what the Reverb Spheres does, except it does so in a non-3D and spatialized way. It gives one audio source reverb--not an entire area.

Select the audio source that you wish to apply the reverb filter to.

Select Component -> Audio -> Audio Reverb Filter. Take note that the filter will not appear in the Listener Line Graph. The parameters can still be adjusted on the fly via scripting.

This filter, contrary to the other PRO exclusive filters, has a hefty amount of parameters. For a full explanation on what each parameter does, visit the Reverb Spheres page and check out the list of parameters for that effect, as they are identical.
